Question one

The current effective vertical stress, ${}^{\text{'}}{?}^v$ at a certain point in a saturated clay is $181$kPa. The soil is to be covered with a $2\mathrm{.}5m$ thick fill that will have a unit weight of $19\mathrm{.}3k\frac{N}{m^3}.$ What will be the value of ${}_v^{\text{'}}$ at this point:

i$.$ immediately after the fill is placed

ii$.$ after the consolidation settlement is complete

iii. when $40\%$ of the excess porewater pressure has dissipated
